HUIF, OF CHICAGO, ILLINOIS, ASSIGNOE TO UNIVERSAL OIL PRODUCTS COMPANY, OF CHICAGO, ILLINOIS, CORPORATION OF SOUTH DAKOTA APPARATUS FOR REMOVING CARBON DEPOSITS FROM OIL APPARATUS Application filed July 22, 1925, Serial No. 45,364. Renewed February 2, 1929.

One of the disadvantages resulting from the use of tube and drum processes of the type wherein vertical reaction chambers are employed is the difliculty of removal of the relatively deep deposits of carbon which accumulate in the reaction chamber.

This invention relates to improvements in -an apparatus for disrupting and removing the carbon deposits from the vertical reaction chamber of this general type.

One object of the invention is to provide an apparatus relatively simple in character that can be readily applied to the reaction chamber and which will eifectively disrupt the mass of carbon deposited in such chamber during the run of an oil cracking process. More specifically, the invention contemplates the positioning in a reaction chamber of diagonally disposed flexible elements extending from the op to the bottom thereof which may be with rawn from the chamber to disrupt the carbon deposits.

In the drawings,-

Figure 1 is a vertical sectional view, of a vertical reaction chamber showing my invention applied thereto.

Fig. 2 is a horizontal sectional View of the structure shown in Fig. 1.

The reference character 1 designates the enlarged vertical reaction chamberof the type generally employed in tube and drum oil cracking processes. The chamber 1 is provided with an oil inlet 2 discharging highly heated oil from a continuous coil, for instance, which inlet may be controlled by throttle valve 3. A vapor outlet 4 leads to a suitable dephlegmator or condenser (not shown). .The chamber 1 may be provided with the usual man-hole covers at the top and bottom, as indicated by reference characters 5 and 6 in Fig. 1.

Coming more specifically to the novel features of my invention, I suspend a flexible metallic member 7 indicated as a chain in the drawing from the hooks or fastenin devices 9 which may be disposed around t e inner periphery of the opening in the top of the expansion chamber. At spaced intervals along the length of the flexible element 7' I may attach separate chains indicated in the drawing b the reference character 8, which chains pre erably extend diagonally from the flexible member 7 to the hooks or fastening detach separate chains indicated in the raw ing as 12, which chains preferably extend diagonally through the chamber to the top thereof and may be attached to hooks or fastening devices shown at 13. The connections between the chains 12 and the fastening devices 13, as well as between the chains 8 and the fastening devices 10, are releasable. These connections may be effected by employing a relatively light gauge wire which can be readily severed when high tension is applied for the purpose of withdrawing chains. The arrangement is such that the chains 12 preferably extend across the center of the chamber and so that they occupy a crisscross position with respect to the chains 8. It will be seen that the flexible member 7 and the chains 8 may be readily withdrawn through the top of the chamber when the cover 5 is open, while the member 11 and the chains 12 can be withdrawn through the bottom of the chamber when the cover 6 is open. I have shown and described the flexible elements as chains. It is understood that I may use metallic cable or the like. Further, it is obvious that flexible member 7 with the downwardly depending flexible elements 8 and member 11 with flexible elements 12 may be used independently and separately, if found desirable, by e iminating the other. It is also understood that the removal of the elements described, particularly from the lower end of the chamber, will not only disrupt the carbon body therein, but will also remove substantial portions of the body simultaneously with withdrawal.

By employin my improvedapparatus the entire mass of eposited carbon in the chamber may be very efiectively disrupted and can then be readily removed.

What I claim as my invention is:

1. An apparatus for disrupting carbon de posits accumulating in the reaction chamber of an oil cracking apparatus, comprising a pair of endless flexible elements, one ofsaid flexible elements adapted to be releasably positioned at the top of the chamber and the other adapted to be releasably supported at the bottom of the chamber, a plurality of independent flexible members connected at one end to said endless flexible elements at spaced points thereof, the independent flexible memers secured to the flexible element positioned at the top ofthe chamber adapted to extend downwardly through the chamber and to be relea'sably connected to the bottom thereof, the same being removable through the to of said chamber, the separate flexible mem rs secured to the flexible element supported at the bottom of the chamber adapted to extend upwardly through the chamber and to be releasably secured to the top thereof and removable from the bottom of the chamber.

2. An apparatus for disrupting carbon deposits accumulating in the reaction chamber of an oil cracking apparatus, comprising an endless flexible element adapted to be releasably supported adjacent a normally closed enlarged openingin the chamber, a plurality of independent flexible members secured to said endless flexible element at spaced points thereof, said independent flexible members adapted to extend through 'said chamber and be releasably secured to the oppositeend thereof, whereby said endless flexible element and said independent flexible members may be removed from the opening in said chamber as a unit.
